3.1.2 Effect of plateau pika disturbance on plant species
richness
Site and disturbance had significant effects on plant species richness
(Table 1), whereas their interaction had no significant effect on plant
species richness. On the overall scale or on the individual site scale,
the plant species richness in the disturbed plot was higher than that in
the undisturbed plot (Figure. 2A; Figure. 2B).
